Fellow geeks... pack away your Doctor Who DVD box sets, file away your comic books, put your action figures back on the shelf and abandon all plans to... y'know... actually go out - because this weekend is officially as good as telly gets for us lot.

Not only is Channel 4 unleashing a fantastically nerdy double-bill on us this Friday (September 27), but BBC One is then following up it up on Saturday (September 28) with the launch of a new fantasy drama that's promising to fill that still-present Merlin-shaped hole in our hearts...

"It's Marvel Studios's first television show and that in and of itself makes it something to look out for," Chloe Bennet, who plays hot hacker Skye, says of the hotly-anticipated Agents of SHIELD. "If you love the Marvel movies, it's all that but just on a smaller screen."

Having had a sneak peak at the pilot episode, the Week in Geek can indeed confirm that SHIELD is essentially The Avengers on the small-screen - there's plenty of action, but it's also very funny, with an impossibly cool cast spouting a wealth of witty Whedon one-liners.

"I think it's got a bit of everything," says Elizabeth Henstridge, who plays adorable SHIELD agent Simmons. "[There's] the comedic element, the drama, the big set pieces, and then the relationships."

Dry those tears - it may be our final trip to Reynholm Industries, but we've still got one last hour-long special - written and directed as ever by Graham Linehan - to enjoy...

It's all a little bit 'as you were' when we picked up with our old chums - Roy (Chris O'Dowd) is trying to keep the attentions of an attractive lady in the higher eschelons of the building, Moss (Richard Ayoade) is making awkward YouTube videos, Douglas (Matt Berry) is being a flamboyant and slightly clueless douchebag (of course), and Jen (Katherine Parkinson) is doing her best to hold it all together.

But when an unfortunate incident with a barista and a homeless person ends up plastered all over the Internet, it seems like The IT Crowd are headed even lower than the basement - until an unlikely hero saves the day...

So the secret's out - Atlantis hero Jason (Jack Donnelly) is no ordinary 'Greek hero'... he's a young man from the modern-day! In search of his father, Jason finds his way to the city of legend... but if you want to know exactly how he comes to leave the 21st century and befriend Hercules (Mark Addy) and Pythagoras (Robert Emms), then you'll have to tune in on Saturday night.

When we meet him he's a newcomer to Atlantis, [and] the audience will discover Atlantis through his eyes," says series lead Donnelly. "As a person he becomes more defined through his relationship with Pythagoras and Hercules. They are the first real friends he's ever made as he never really fitted in where he came from."

Game of Thrones veteran Addy - playing a rather unconventional Hercules - adds: "There's action, there's adventure, friendship, loyalty, fate and destiny - there's a whole bunch of things which... makes it into a roller coaster of a show!"
